A bursa is a closed, fluid-filled sac that functions as a cushion and gilding surface to reduce friction between tissues. The major bursae are located adjacent to the tendons near the large joints,such as in the shoulders,elbows,hips and knees. When the bursa becomes inflamed, the condition is known as bursitis. Bursitis is usually a temporary condition. It may restrain motion, but generally does not cause deformity.

  • injury or overuse
  •  Arthritis
  • Gout
  • Tendinitis
  • diabetes
  • thyroid disease.

Symptoms of bursitis

  • pain
  • localized tenderness
  •  limited range of motion.
  • Swelling and redness may occur if the inflamed bursa is close to the surface (superficial).

Chronic bursitis may involve repeated attacks of pain,swelling and tenderness which may lead to the deterioration of muscles and a limited range of motion.
